PS150/CH150 12 V Charging Regulators
100% to 50% approximately doubles the number of useful cycles available
from the battery 1 .
Leaving a lead-acid battery in a discharged state for
prolonged periods of time results in the undesirable growth
of large sulfate crystals (sulfation) that are detrimental to
battery performance.
VRLA batteries self-discharge at approximately 3% of rated capacity per
month at room temperature 1 . A 3% of rated capacity per month self-discharge
results in 100% discharge in approximately 33 months (≈ 3 years) for a battery
stored at room temperature. Self-discharge increasing with increasing storage
temperature.
Periodic recharging of stored batteries every few months is
recommended to prevent irreversible sulfation due to prolonged
time in a discharged state.
3. Quick Start
The PS150/CH150 modules are designed to handle extreme conditions. The
modules have been designed with mounting holes on one inch centers for
mounting to a standard Campbell Scientific enclosure back plate — see the
enclosure manual for mounting suggestions. See FIGURE 3-1 through
FIGURE 3-3 for typical enclosure installations using a PS150/CH150.
